Chrome ore is a combination of iron and chromium oxides, feo. cr2o3. the ore is reacted with soda ash* and oxygen from air at 1000°c to produce soluble sodium dichromate, which can then be dissolved out leaving an insoluble residue. a simplified reaction mechanism is shown below. 4fe0.cr203+8na2 co3 + 702 > 8na2cro4+ 2fe203 + 8co2 solid solid solid solid gas gas discuss the factors affecting reactor choice. determine the most suitable reactor for the process, fully justifying your choice. [5] note: soda ash melts at 851°c and softens in the 650-700 c range fthulono

Which substances have the lowest melting points: ionic covalent, or metallic

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here. (score for question 3: of 5 points) were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. type your answer here. (score for question 4: of 5 points) make a general statement about the reactivity of the metals in this experiment. type your answer here.
